TERMINAL FOB BUSH-BUTTON ELECTRIC SWITCHES.

Application filed September 21, 1909. Serial No. 518,869.

To all whom it may concern: B e 1t known that I, NORMAN MARSHALL, a citizen of the United States, residing at West Newton, in the county of Middlesex and State of Massachusetts, have invented a new and useful Im rovement in Terminals for Push-Button lFllectric Switches, of which the following is a specification.

This invention relates to the construction of a terminal, or stationary contact and binding post, of an electric push button switch.

The object. of the invention is to provide a terminal with a contact-blade and binding post of approved type and efficiency, formed in a single piece in such manner that the saine terminal may be used either for hi h contact or low contact in the receptacle 0 a push button'switch.

Figure 1 of the accompanying drawings shows a transverse section of a push button switch receptacle provided with a terminal which embodies thip. invention. The terminal is shown as fastened in this section of the rece tacle with the contact blade high. Fig. 2 Shows a transvcrsesection of a push button switch receptacle with a terminal which embodies this invention arranged Fig. 3 shows a longitudinal section of a1 push button switch receptacle with two terminals which embodythis invention arranged therein, one

being arranged with the contact blade high, and the other with the contact blade low. Fig. 4 shows an edge elevation of the terminal. Fig. 5 shows a plan and Fig. 6

shows a front view of the terminal.

This terminal is preferably stamped to shape of brass with a standard section 1. The ends 2 of the strip which ,forms the standard section are bent at right angles therewith. Each of the bent ends is provided with a threaded perforation 3, that at one end being adapted to receive the binding screw 4 or the attachment of the end of a circuit wire, and that at the other end being adapted to receive the fastening screw 5, by means of. which the terminal is secured in the receptacle 6. Lugs 7 are bent at right angles with the tips of the ends for the purpose of preventing the circuit wire from sliding out from beneath the bindin screw when that screw is being set down for fascontact plates when they are thrown thereon.-

This terminal, which is punched from a single piece of conducting material, may be fastened one end up so as to provide for a high contact, or it may be fastened the other end up so as to provide for a low contact, as illustrated in the views. This Patented Apr. 12, 1910.

oles or contact construction enables a terminal to be made I which will answer for either end of a push button receptacle without change of form, thus enabling large quantities-to be 'produced very rapidly and cheaply with a single set of tools, and readily assembled without liability of placinga wrong contact in a receptacle.

The invention claimed is:

1. A terminal for an electric snap switch formed of a single piece of c'onducting'inaterial and having a standard section with the ends thereof bent atright anglesthere to, each of said ends having a perforation therethrough, and a contact blade project ing from one edge of the standard section:

in. the plane thereof.

2. A terminal for an electric snap switch formed of a single pieceof conducting material having a standard section with the ends thereof bent at right angles thereto, each of said ends having a threaded perforation therethrough, and a contact blade projecting from one edge of the standard section in the plane thereof.

3. A terminal for an electric snap switch formed of a single piece/of conducting material and having a standard section, with the ends thereof bent at right angles there- -to, each of said ends having a threaded perforation therethrough, lugs projectin at an angle from the ends, and a contact bfade projecting from one edge of the standard section in the plane thereof.

4. A terminal for an electric switch contact blade projecting from the edge near formed of a single piece of conducting maone end of the standard section in the plane terlal and having a standard section with thereof.

the ends thereof bent at right angles there- NORMAN. MARSHALL. to, each of said ends having a threaded Witnesses: perforation therethrough, lugs projecting at M. A. MAR'IENS,

an angle from the tips of the ends, and a E. A. DANIELS.
